Thanksgiving sale ends on 12/1/2024!

Important: if you have Gaggia Classic EVO Pro (2023), please scroll down to see Note 6 before you place your order.

Update: This kit is compatible with the latest Gaggia Classic EVO Pro (released in 2023) and Gaggia Classic Pro (released in 2018/2019) models, including the regular model (RI9380, 120V or 240V) and the European model (RI9480, 240V). Please see the compatible model list below (Note 1 on the bottom). European model Gaggia Classic 2015 (RI9403, 240V) is NOT compatible. Please check KIT-GGX-EU instead. 

The KIT-GG is a retrofitting kit designed to control the coffee water temperature on an espresso machine. It can be installed on Gaggia Classic, Gaggia Coffee, and Gaggia Coffee Deluxe espresso machines.

Main Feature. The coffee water temperature in the boiler of a home espresso machine is originally controlled by a bi-metal thermostat, which causes a big temperature swing. The KIT-GG PID controller kit replaces the function of the mechanical coffee thermostat. After the kit is installed, the standby brew water temperature can be controlled to within ±1° (F or C) accuracy. Thus, it will significantly improve the taste and consistency of your espresso. Users can see the boiler temperature on the PID controller directly and also easily adjust the brew water temperature to suit their own tastes.

• Monitor and display the boiler temperature precisely. 
• Regulate the standby coffee water temperature to within ±1° (F or C) accuracy.
• Allow easy adjustment on the coffee water temperature. 
• Greatly improved the taste and the consistency of brewed espresso shot. 
• All buttons on the Gaggia machine function the same way as they were. 
• The kit installation is fully reversible. 

This kit doesn't control the steam temperature nor has the pre-infusion function. If you also need features such as steam temperature control, pre-infusion, and countdown timer, please check KIT-GGP pre-infusion kit. 

LED display color. The digital LED display module is available in red or white. 

Box color. Two different colors of the controller box are offered, silver and black. The silver box is coated with clear anodized aluminum with a brush-finished stainless steel front panel. It is suitable for Gaggia Classic or other machines with a silver finish. The black box has a durable powder coating. It is suitable for other colored espresso machines.  

Temperature unit. Select the preferred temperature unit so that all parameters are pre-set properly for you.

Power input. The kit is compatible with both 110VAC and 240VAC power.
